Description
Technical field
The utility model relates to a kind of solid-liquid separating equipment, especially relates to a kind of interposed membrane formula autoclave diaphragm filter plate.
Background technology
Along with the develop rapidly of Chinese national economy, sewage treatment plant is also in constantly building, and its quantity is also increasing rapidly.The large number of biological mud that can produce in sewage disposal process, is badly in need of concentrating harmless treatment.The way of lignin-sludge has multiple, as landfill method, burning method and composting process etc. both at home and abroad at present.Due to environment and economy reason, utilize mud to contain the content of organic matter high, the characteristic that viscosity is good carrys out the method that brickmaking or sintering ceramsite become most practicality in recycling sludge.The key technology of recycling sludge brickmaking is sludge dewatering, and this cost being not only related to brickmaking also determines the technical feasibility of the method.Chinese patent discloses a kind of composite board frame type mud press-filter dryer (Authorization Notice No.: CN 2464424Y), it adopts the movable overlapping of many groups and the mainboard frame leaned on, the filter chamber that a large regions is recessed is respectively established before and after this mainboard frame, and through sludge inlet before and after, and preset limber hole at the corner of mainboard frame; Respectively a complementary shaped is installed but the subplate frame of little thickness between this two mainboards frame, and each subplate circle body forms a hollow region by circumferential side frame, respectively in conjunction with a whole surface elastic diaphragm before and after framework, the hollow region inside of framework is made to form a confined space, and through sludge inlet before and after, separately through before and after the corner of subplate frame is preset limber hole; This subplate circle external week is respectively equipped with a hot air inlet, a heat extraction pore, and is all communicated to above-mentioned confined space, for extraneous hot gas input heating and urgent Zhang Qianhou flexible sheet, makes the moisture content vaporization of the inner mud of filter chamber; This subplate circle external week separately establishes a pressurization air inlet/outlet; This hot air inlet, heat extraction pore system are located at two relative edge's frame places of framework; This subplate circle body directly makes above-mentioned sludge inlet.But the membrane filter plate that this filter press adopts is in use because membrane filter plate and solid slab are that polylith combination forces together, therefore require very high to the material of diaphragm plate elastic diaphragm, will meet simultaneously there is higher elasticity, toughness, intensity and rigidity.Squeeze pressure is higher, and moisture content of the cake is lower, and therefore diaphragm plate will bear larger pressure, and therefore its service life is shorter, and the excessive filter plate of pressure can be out of shape, thus causes mud to spill, and limits the squeeze pressure of feed pressure and diaphragm plate so technically.
Utility model content
The utility model is to provide a kind of interposed membrane formula autoclave diaphragm filter plate, its membrane filter plate mainly solving the filter press employing existing for prior art is in use because membrane filter plate and solid slab are that polylith combination forces together, therefore require very high to the material of diaphragm plate elastic diaphragm, to meet simultaneously there is higher elasticity, toughness, intensity and rigidity, service life is shorter, the excessive filter plate of pressure can be out of shape, thus cause mud to spill, limit the technical problem of the squeeze pressure of feed pressure and diaphragm plate etc. so technically.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Interposed membrane formula autoclave diaphragm filter plate of the present utility model, comprises intermediate plate, described intermediate plate inner hollow or solid, the both sides of intermediate plate are respectively equipped with one piece of diaphragm, the two sides of intermediate plate is spill, and the periphery of diaphragm is fixed on the spill place on intermediate plate two sides, and intermediate plate has charging hole.Because diaphragm is built in the recess position of intermediate plate, lower than or with intermediate plate surrounding edge on a plane, therefore intermediate plate periphery protuberance can first with adjacent intermediate plate, thus bear pressure, and sealing is also completed by the periphery projecting ends of adjacent intermediate plate.Such diaphragm itself does not bear the pressure that sealing compresses, and its need bear elastically-deformable pressure.Therefore in selection, intermediate plate only need select sealing better, the material of the stronger anti-high pressure of rigidity, diaphragm then need select the material that elasticity, tough factor are higher, without the need to taking into account high strength, high resiliency requirement more simultaneously.Reduce the technical difficulty of Material selec-tion.And existing filter plate mechanism to be all two pieces of adjacent diaphragms rely on its end to contact, thus rely on diaphragm to complete elastic deformation, sealing, measuring body work, therefore selection is more difficult.The utility model overcomes current filter press pressure techniques bottleneck, learnt by practical application, feed pressure can up to 1.8MPa, and squeeze pressure can reach 3.0MPa, and push pedal compaction pressure can reach 30MPa.The work being compressed by intermediate plate, sealed, thus extend service life.
As preferably, the spill place of described intermediate plate all has corresponding embedding groove with on the periphery of diaphragm.Diaphragm can be fixed by the mutual embedding groove of engaging and the spill place of intermediate plate, thus comparatively firm regularly.
As preferably, described embedding groove is circular arc or zigzag.Embedding groove can be a rectangular channel, also can be zigzag, and also can be an arc-shaped slot, it also can be the groove of other shape of up concave type, its objective is to make diaphragm and intermediate plate be fixed together better.
As preferably, the outer surface plane of described diaphragm and the planes align of intermediate plate protuberance; Or the outer surface plane height of diaphragm is lower than the level of intermediate plate protuberance.The outer surface of diaphragm does not protrude intermediate plate, therefore intermediate plate directly with adjacent intermediate plate, thus sealing is better, also prevent the pressure that diaphragm bears compression.
As preferably, the periphery of diaphragm is fixed by welding in the spill place on intermediate plate two sides.By welding, make diaphragm and intermediate plate more firm regularly, and sealing is better.
As preferably, the shape of described intermediate plate periphery section is T-shaped, Y-shaped or circular arc.The section of intermediate plate periphery also can be the sealing surface of other shape, its objective is to seal better in order to intermediate plate and diaphragm are formed.
Therefore, the utility model is by being designed to concave shaped by intermediate plate, make in whole filter plate mechanism with intermediate plate bear compression, sealing work, diaphragm only need bear elastically-deformable pressure, thus make selection of the present utility model comparatively simple, save production cost, extend service life, simple and reasonable for structure.
